本文提出了一种先进的频谱数据库的概念，通过测量无线电环境的传感器上的车辆。在当前由美国联邦通信委员会（FCC）规定的TV白色空间频谱数据库的设计中，利用传播模型来决定频谱的可用性。为了确保对主用户（PU）的保护，这种方法需要PU覆盖区域的大余量。在所提出的数据库中，无线电信号的实际测量值用于生成数据库。由于移动车辆上的传感器收集大量的数据，可以获得准确的传播状态，包括传播损耗和阴影。在本文中，我们介绍了先进的数据库的概念，并提出了实验数据库生成使用实际的电视广播信号的初步结果。
This paper proposes a concept of advanced spectrum database generated through the measurements of radio environment from sensors on vehicles. In the current design of TV white space spectrum databases, which is regulated by the United States Federal Communications Commission (FCC), a propagation model is utilized to decide on the availability of spectrum. To ensure protection of primary users (PUs) this approach requires a large margin for the PU coverage area. In the proposed database, the actual measurements of radio signals are used to generate the database. Since the sensors on moving vehicles gather large amount of data, an accurate propagation status can be obtained, including propagation loss and shadowing. In this paper we introduce the concept of advanced database and present initial results of experimental database generation using actual TV broadcast signals.
